SCLC is categorized into different subtypes based on the expression levels of the transcription factors achaete‐scute complex like protein 1 (ASCL1), neuronal differentiation 1 (NEUROD1), and POU domain, class 2, transcription factor 3 (POU2F3), as well as their inflammatory characteristics.[80] Recognition of subtype‐specific molecular profiles can facilitate the development of novel targeting strategies. Here, NEUROD1 is linked to small cell lung carcinoma.
